ƒ The free length of supply wire inside the electrical enclosure must be at least 6 inches
(150 mm).
ƒ When connecting external supply voltage to the electrical enclosure, installer must
select appropriate hardware to maintain NEMA 4x rating.
ƒ Panel must be connected to a properly grounded electrical supply.
ƒ An electrical disconnect must be provided for the panel:
– It must be suitably located (e.g., close to the panel) and easily reached.
– It must be marked as the disconnecting device for the panel.
Operation
Unit will be hot during normal operation .
Starting Up
1. Establish cooling water flow.
2. Initiate sample flow through the reboiler.
3. Adjust sample flow to 100–150 cc/min.
4. Turn the heater power switch SW-1, to "ON. "
5. Verify that the indicator lamplight and the display on the controller are functioning.
6. Allow sample to flow through the unit to stabilize (about 10 to 15 minutes).
 NOTE
The indicator light cycles on and off with the heater .
Adjusting the Controller
The controller has been preprogrammed at the factory. If additional trimming of the
controller is required, the heat range setting should be between 223°F and 226°F (106°C
and 108°C) based on sample flow rate.
When the heater and flow rate are set properly, condensed water should trickle out from
the condensate drain.
ƒ If no condensate is seen, reduce the sample flow rate or increase the temperature
setpoint until the rate of condensation is constant.
ƒ If droplets of hot boiling water are seen venting from the condensate drain, either
reduce the temperature setpoint or increase the flow rate.
ƒ Adjustments should be within the specified ranges for flow rate and temperature
